# Replicate Transform

The replicate transform replicates a Pandas DataFrame. It will replicate it once for each asset in the *asset_list*. It will also add an ‘asset’ column that contains the name of the asset.

**Example:**

Say we have a DataFrame that looks like this:

```actionscript
some_field,stream_type,timestamp
3.14      ,'a_stream' ,2018-01-01 00:00:00.000000
2.71828   ,'b_stream' ,2018-01-02 00:00:00.000000
0.0       ,'my_stream',2018-01-03 00:00:00.000000
```

And we want to replicate it for three different assets:

```actionscript
asset   ,some_field,stream_type,timestamp
'asset1',3.14      ,'a_stream' ,2018-01-01 00:00:00.000000
'asset1',2.71828   ,'b_stream' ,2018-01-02 00:00:00.000000
'asset1',0.0       ,'my_stream',2018-01-03 00:00:00.000000
'asset2',3.14      ,'a_stream' ,2018-01-01 00:00:00.000000
'asset2',2.71828   ,'b_stream' ,2018-01-02 00:00:00.000000
'asset2',0.0       ,'my_stream',2018-01-03 00:00:00.000000
'asset3',3.14      ,'a_stream' ,2018-01-01 00:00:00.000000
'asset3',2.71828   ,'b_stream' ,2018-01-02 00:00:00.000000
'asset3',0.0       ,'my_stream',2018-01-03 00:00:00.000000
```

Our configuration will look something like this:

```actionscript
{
    "transform_name": "Replicate",
    "transform_type": "replicate",
    "filter_stream": [
        "*"
    ],
    "asset_list": ["asset1", "asset2", "asset3"],
}
```

**Configuration:**

**Required** and *optional* properties that can be configured for a replicate transform.

- **asset_list**: The list of assets that will be added to the DataFrame
- **transform_name**: Unique name for the transform.
- **transform_type**: Type of transform to apply. Should be replicate.
- **filter_stream**: List of data streams to transform. Each stream can either be * (all) or asset:stream.
